COMBING-MAGHINE.

Specification of Letters Patent.

Patented J unc 21, 1921.

Application filed January 28, 1920. Serial No. 354,675.

To all whom it may concern:

Be it known that 1, James Honnmen, a subject of the King of Great Britain, residing at 336 Bridgeman street, Bolton, in the county of Lancaster, England, have invented new and useful Improvements in Combing-f/lachines, of which the following is a specification.

This invention relates to improvements in combing machines and has for its object to simplify and improve the method of and means for actuating the detaching rollers.

In combing machines of the Hellman type it is customary to employ a group of three detaching rollers and in combing machines of the Nasmith type it is customary to employ a group of four detaching rollers. In the former case as is well understood one of these rollers (the prime mover) transmits its motion by frictional contact to the other two rollers whereas in the Nasmith system, the two bottom rollers are geared together, while the upper rollers are driven by frictional contact with their respective bottom rollers.

Hitherto it has been customary to employ somewhat complicated arrangements of mechanism for imparting the required partial reverse and subsequent forward revolutions to the prime mover of the detaching rollers.

One such arrangement comprises a cam, clutch mechanism, and quadrant, while another mechanism comprises a cam operating a catch lever, and a spring catch acting in conjunction with a notched wheel.

According to my invention I dispense with such complicated mechanisms and impart the necessary partial reverse and forward rotations to the detaching roller through the medium of a three armed follower or triangular plate carried on the axis of the detaching roller or'an intermediate axis and actuated by a hollow cam of a special construction designed to effect the full cycle of operations in one revolution.

I illustrate my invention in the accom panying two sheets of drawings, in which-' Figure 1 is an end elevation of my improved mechanism for actuatnig the detaching rollers of a combing machlne, and Fig. 2 is a side elevation of the same.

In these views,-a designates the combing cylinder shaft; 1) the hollow cam which is fixed thereon; c the three armed follower or triangular plate having at its apices or outer extremities three rollers d (Z d mounted and free to rotate upon studs 6; and f the intermediate shaft upon which the three armed follower or plate 0 is keyed; g the bottom back detachingroller; h the spur wheel; and 11 the pinion by which the intermediate shaft ,1 is geared to the detaching roller 9.

The following is the cycle of operations At the beginning of the cycle as the cylinder a rotates in the direction indicated by the arrow Fig. 1 the roller CZ carried by one of the arms of the follower or plate 0 comes into contact with a swell or incline 1 on the rotating hollow cam 5; this swell 1 is so shaped as to impart a gradual start in the reverse direction to the bottom back detaching roller 9' increasing to full speed before another incline 2 on the rotating cam comes into contact with another roller say (Z on an arm of thefollower. This second incline 2 is shaped to maintain the movement of the follower c and detaching roller 9 at full speed in the reverse direction until the continued rotation of the cam Z) brings other inclines 3 and 1 into contact with the rollers (Z 0Z on the follower and causes a stop of the detaching roller and a reverse or start in the forward direction. The remaining inclines or tappets on the cam 5, 6, 7, 8 act as plain gearing to effect the rotation of the bottom back detaching roller 9 in the forward direction for the required amount of rotation while finally an annular groove 8 concentric with the axis a of the rotating cam b engages and locks one of the rollers d d d and so locks the follower o and detaching roller 9' for the remaining portion of the revolution of the cam h prior to re-starting the cycle already specified.

From the foregoing description it will be readily understood that the mechanism is smooth in action and is in no way liable to get out of order as there are no catches, springs or clutches, and consequently no risk of any parts sticking as the follower c (and consequently the detaching roller 9) is positively controlled throughout the whole cycle effected in one revolution of the cam 79.

I have shown and described a three armed follower but I might employ a follower or equivalent with two or four arms and although I have shown the three armed follower or triangular plate carried on an intermediate axis it might be on the axis a of the detaching roller as already ,indiback 'detachingroller it might be equally.

cated,

Further instead of applying my improved mechanism to' actuate the bottom well applied to the front bottom detaching roller and further I reserve the right to apply it to any other detaching roller if found convenient or advantageous.

What I claim as my invention and'desire to secure by Letters Patent of the United States is 1- V 1. In a combing machine, the combination of a combing cylinder, a detaching roller, an intermediate shaft between said cylinder and roller, gearingbetween said shaft and roller, a member securedto said shaft" for rotation therewith and having a plurality ofarms, and a hollow cam member carried by said cylinder for rotation therewithand provided with cams disposed in the path of said arms thereby'to impart shaft for rotation therewith andhaving a plurality of arms, and a hollow cam member carried by said' cylinder for rotation therewith and provided with cams disposed in the path of said arms thereby to impart to said shaft a variable speed of rotation in one direction and then cause the rotation of the shaft to cease and thereafter to rotate in the opposite direction, all of said operations of the shaft'occurring during the rotation of the cylinder in one direction. 7

3. In a combing machine, the combination of a combing cylinder, a detaching roller, an intermediate shaft between said cylinder and roller, gearing between said shaft and roller, a member secured to said Shaft for rotation therewith and having a plurality of arms and a hollow cam member carriedby said cylinder for rotation.

therewith and provided With cams disposed in thepath of said arms thereby to impart to said shaft rotation in one direction at gradually increasing speed and to maintain said speed for av predetermined 7 time, then causing the rotation of the shaft.

to cease and thereafter rotate the shaft in the opposite direction, all of said operations of the shaft occurring during rotation of the cylinder in one direction.

In testimony whereof I have signed my nameto this specification in the presence of two subscribing witnesses. V
